Cathelicidin

Cathelicidin-related antimicrobial peptides are a family of polypeptides found in lysosomes of macrophages and polymorphonuclear leukocytes (PMNs), and keratinocytes. Cathelicidins serve a critical role in mammalian innate immune defense against invasive bacterial infection. The cathelicidin family of peptides are classified as antimicrobial peptides (AMPs). The AMP family also includes the defensins. Whilst the defensins share common structural features, cathelicidin-related peptides are highly heterogeneous.

Members of the cathelicidin family of antimicrobial polypeptides are characterized by a highly conserved region (cathelin domain) and a highly variable cathelicidin peptide domain.

Cathelicidin peptides have been isolated from many different species of mammals. Cathelicidins were originally found in neutrophils but have since been found in many other cells including epithelial cells and macrophages after activation by bacteria, viruses, fungi, or the hormone 1,25-D, which is the hormonally active form of vitamin D.

Poté

Poté is a Brazilian municipality located in the northeast of the state of Minas Gerais. Its population as of 2007 was estimated to be 14,749 people living in a total area of 632km². The city belongs to the mesoregion of Vale do Mucuri and to the micro-region of Teófilo Otoni. It became a municipality in 1938.

The name is derived from a semi-legendary figure called Poté, who was an indigenous leader of the Botocudo, the first inhabitants of the region.

The main economic activities are services, small industries, and agriculture. A large percentage of the population lives in the rural area and is engaged in subsistence farming. The GDP in 2005 was approximately R$42 million, with 30 million from services, 3 million from industry, and 6 million from agriculture. There were 513 rural producers on 24,000 hectares of land. Only 24 farms had tractors (2006). Approximately 1,500 persons were dependent on agriculture. The main cash crop was coffee while sugarcane, beans and corn were grown on a small scale. There were 27,000 head of cattle (2006). There was one bank (2007) and 562 automobiles (687 motorcycles), giving a ratio of 26 inhabitants per automobile.

Pot (poker)

The pot in poker refers to the sum of money that players wager during a single hand or game, according to the betting rules of the variant being played. It is likely that the word "pot" is related to or derived from the word "jackpot."

At the conclusion of a hand, either by all but one player folding, or by showdown, the pot is won or shared by the player or players holding the winning cards. Sometimes a pot can be split between many players. This is particularly true in high-low games where not only the highest hand can win, but under appropriate conditions, the lowest hand will win a share of the pot.

Potentiometer

A potentiometer, informally a pot, is a three-terminalresistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.

Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.

Nomenclature

There are a number of terms in the electronics industry used to describe certain types of potentiometers:

slide pot or slider pot: a potentiometer that is adjusted by sliding the wiper left or right (or up and down, depending on the installation), usually with a finger or thumb
